I am still concerned about having warranty issues if I do a tune on my car. Has anyone actually confirmed whether or not the dealer can tell if a tune has been done once it has be reflashed back to stock?

Thanks

 

Please do a search and read the threads on this subject. If you are not familiar with how to do this just ask us. If you do not feel easy about it just do not do it. The car is yours not ours. THE FACTS are You can take the tune out, restore the factory settings, disconnect the battery for half hour or so and your dealer cannot tell you did anything.
Friday I was told by a local shop to turn on the lights after disconnecting the battery because there was a temporary memory battery somewhere in the system. This was the first I knew of this. Maybe someone can give us a heads up on this.
By the way when you disconnect the battery, Take off the ground minus side off the battery not the positive side.

 

I was at my dealer last weekend for my 5,000 mi checkup. I told me dealer about my flowmasters, C&L, and tune... he just laughed and said nice
